The ACAS design offers significant advantages compared to discrete resistor types. The resistive elements are an extremely stable thin-film resistive alloy with meander trimming. The trimming geometry allows the resistor to homogeneously dissipate power and distribute thermal energy across the entire resistive element. This enhances the stability of the ACAS components to a low resistance drift of ≤ 0.1% after a 1,000-hour load life test by reducing the intensity of single hot spots on the resistive film elements when the resistor is in use.
